Service interface

About this task

Within Eclipse:

Procedure

  1. Create a Maven project, following the same steps as in this section, and call it locator_common for the purposes of this example.
  2. Remove all default sources, as well as test source folder.
  3. Create a package named demo.common, and create an interface Greeter.java: 
    package demo.common;

import javax.jws.WebService;

@WebService(targetNamespace = "http://talend.org/esb/examples/", 
        name = "Greeter")
public interface Greeter {
    String greetMe(String requestType);
}
    Greeter.java will be the service interface. The project structure will look like this:

    Example

  4. The common application will be deployed as an OSGi bundle. You will need to edit the pom.xml file. 
    <project xmlns="http://maven.apache.org/POM/4.0.0" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
                        http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.talend.liugang.cxf</groupId>
    <artifactId>locator_common</artifactId>
    <version>1.0.0</version>
    <packaging>bundle</packaging>
    <name>locator_common</name>
    <url>http://maven.apache.org</url>

    <dependencies>
        <dependency>
            <groupId>org.apache.felix</groupId>
            <artifactId>org.osgi.core</artifactId>
            <version>1.4.0</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <extensions>true</extensions>
                <version>2.3.7</version>
                <configuration>
                    <instructions>
                        <Bundle-SymbolicName>
                            ${project.artifactId}
                        </Bundle-SymbolicName>
                        <Export-Package>
                            demo.common
                        </Export-Package>
                    </instructions>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>
  5. Now that you have finished the definition of the service, select Run As > Maven Install from the M2Eclipse Popup menu on the pom.xml to install the application into your Maven repository.
    The next step is to implement this service.
